An Anti-Epileptic drug taken for nerve pain and seizures. It's also the *pain* medicine doctors all over the US are chucking out to patients like candy, when they don't want to prescribe anything good. Makes you feel like your drunk and dumb.

Dude, I just took two gabapentins and I feel loopy and wasted as shit.
And not a good type of loopy and wasted like shit. Like... sloppy wasted.
